Random Issue in accessing Test-NetConnection inside a job

[RaghavendraP]

I am using a Test-Netconnection function inside my RsJob. It works well most of the times but every now and then I get an error that says: "The 'Find-NetIPsecRule' command was found in the module 'NetSecurity', but the module could not be loaded. For more information, run 'Import-Module NetSecurity'. I am not sure why this happens only few times but not always if its a problem with module import.

By the way I was not using -ModulesToImport argument of RsJob to pass NetSecurity also I believe its not necessary as it works 95% of the times. But if that is needed, I can give it a try.

I briefly look at the Test-NetConnection code and seems it use Find-NetIPsecRule only when it run under UAC-raised admin Please check it and if it is true, try to preload NetSecurity module because as far as I know nobody test nested module loading

I've added the NetSecurity to ModulesToImport and will check if the problem is recurring or not. Thanks.

Also, found any reason why it would fail only few times but not always if this is the case? i create almost 100 jobs with a batch size of 25-30 and get this error only in 2-5 jobs and rest went through fine.

I've heard about random module autoloading problem with rsjob but do not meet it so dont explore it
